From Narrative Official Site, "RGM-89 ジェガンとは別系統で開発された機体であり、装甲も厚い重装型となっている。" . So the two are developed separately.--My girlfriend is a loli. 06:58, March 31, 2020 (UTC)
Good moment to clear some stuff about this particular MS:
1)The different versions MUST have different separate pages as in(this should apply for all the HF machines):
A)HF anime version(whatever official designation/model number it ends up having)
B)Unicorn and Narrative version
C)G Gen redesign version
D)Original novel version
2)The lore from both novel and G Gen redesign is different from the animated version. The animated version is meant to be a successor of the RGM line, not the Jegan itself. This is clearly stated in both official sites for Unicorn and Narrative and in the HGUC manual for the Unicorn version. The animated version was made in a different production line from the Jegan/Jesta but uses the same Beam Rifle and Beam Sabers as the Jegan.
3)There's NO mention of any Dora Karl in the novel, its first mention is in the Gundam Weapons that covered the G Gen redesign. Dora Karl is the standard machine which has a rod-type antenna on the back left of the head, while the Gustav is the commander machine with enhanced communication ability and a single frontal v-fin on the right side of the head in the G Gen redesign setting. The animated version lore makes no mention so far of a Dora Karl or the Gustav being a commander type MS.
4)The HGUC manual for the Unicorn version mentions that there's a light armored version of the Gustav, if this ends up being the Dora Karl for the animated HF version is only speculation for now.
Also Deacon banned for vandalizing pages again. Hopefully this becomes motivation for him to finally finish his "translation" of the novel. Balofo (talk) 07:05, March 31, 2020 (UTC)

I'm not sure about this because Gundam W still has EW ver. lumped with TV ver, but if people want to separate them, I won't object.--My girlfriend is a loli. 08:59, March 31, 2020 (UTC)
Nowadays the merchandise has the "EW Version" label, so yeah this should be done for all the Wing stuff too. The EW stuff also has unique lore now like the Zero Frame. Balofo (talk) 16:58, April 5, 2020 (UTC)
